Puzzle 169 – “That’s Entertainment?”

puz here / pdf here / solution here

Hope your Labor Day weekend was a nice one. Now let’s get themeless.

Seed entries here are the 12-letter ones at 22-Across and 48-Across, the latter of which is, I assure you, a canonically accurate fun fact. Both of them, I guess, gave rise to the slightly dubious-sounding question mark in this week’s title.

Favorite clue here: no doubt, 43-Across (which *is* entertainment)… and in its way, 5-Down is entertainment too.

Hope you’re entertained by this one as well. Happy solving, yall. Comments welcomed, as ever.
